netcdf4 and ncdump

Hello

I'm in the process of re-writing the output routines of a ocean model
from NetCDF3 to NetCDF4.

As part of my efforts I would like to see if I'm actually storing data
in my .nc file. Usually I use ncdump for that purpose but with NetCDF4 I
get:

kbk@orca:~/getm-setups/v1.6.x/haidvogel$ /opt/netcdf4/bin/ncdump getm.nc
netcdf getm {
dimensions:
        lon = 130 ;
        lat = 5 ;
        z = 21 ;
variables:
        float lon(lon) ;
        float lat(lat) ;
        float level(z) ;

// global attributes:
                :title = "Haidvogel and Beckmann test case" ;
                :history = "Generated by getm, ver. 1.7.0" ;
data:

 lon = _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _ ;

 lat = _, _, _, _, _ ;

 level = _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _ ;

group: 2d {
dimensions:
        time = UNLIMITED ; // (48 currently)
variables:
        float time(time) ;
        float elev(time, lat, lon) ;
        float U(time, lat, lon) ;
        float V(time, lat, lon) ;
data:
}
}

Notice that it is listed that there are 48 in the unlimited dimension I
do hwoever not see any data listed. For testing I just dump random
numbers into elev, U and V.

Is that a new feature of ncdump?


Another question - I'm I right in the assumption that I can inherit
dimensions from the root group - as shown above - does that imply I also
inherit the root coordinate variables?
